Title: Recorder
Inventor: YOSHIKAWA HISASHI
IPC: B41J11/42
Filed: 2001-10-01
Abstract: PROBLEM TO BE SOLVED: To improve the transfer accuracy in a recorder having two paper discharge rollers. SOLUTION: A first paper discharge roller is constituted to normally rotate when an LF motor is rotating, and a second paper discharge roller is constituted so as to stop rotation during a transfer operation for recording papers. Before a rear end of the recording paper reaches a specified position after separating from an LF roller, the recording paper is transferred by only the first paper discharge roller, and the second paper discharge roller holds the posture by sliding the recording paper with low friction. After the rear end of the recording paper reaches the specified position, the stopped second paper discharge roller is started to rotate. At this time point, since the whole recording operation is terminated, what affects the image quality is only the first paper discharge roller which rotates normally, and the accuracy of the second paper discharge roller is negligible.  Therefore, the transfer accuracy equivalent to that of a recorder constituted with one paper discharge roller can be realized while advantages of the fact that two paper discharge rollers are used are made use of by improving the transfer accuracy of only the first paper discharge roller.

IPC: G10L21/02
Filed: 2001-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for reducing noise in a training signal or inspection signal. SOLUTION: This noise reducing method uses a stereo signal composed of two channel signals and the channels include the same pattern signal. One channel signal is 'clean' and the other includes added noise. Correction of noise and a set of scaling vectors is determined (308) by using feature vectors (300, 302) from those channel signals. When the feature vectors of the noisy pattern signal are received later, multiplication by the best scaling vector for the feature vectors is performed and the best correction vector is added to the product to generate a noise-reduced feature vector. In one implementation example, when the best scaling and correction vector are specified, the best mixed component for the noise-containing feature vector is selected.  The selection of the best mixed component is performed according to a distribution of noisy channel feature vectors related to respective mixed components.
